Specification of Letters Patent.

Application filed June 29, 1916. Serial No. 106,646.

To all whom it may concern i Be it known that I, HORATIO G. GII LMOR a citizen of the United States, residing at Washington, in the District of Columbia,

which may be used in connection with a tie plate and which when so used will not affect the relations of the rail and the tie platebut will leave the-rail free to move slightly vertically in relation to the tie plate under the wave movement of the rail andat the same time effectually hold the rail against creeping tendencies.

Another object of the invention is to provide a device which shall grip the rail above the surface ofthe ballast and which shall therefore be free from interference with its eflicient action by the ballast.

The preferred form of the invention is illustrated in the accompanying drawings, in which Figure 1 is an end view, showing the rail, tie plate and shoe in section.

Fig. 2 is a side elevation, showing the device in'place with the tie plate in section.

Fig. 3 is a plan view of the device in operative position upon the rail.

Fig. 4c is an end view, showing some of the parts in section, illustrating the manner in which the deviceis applied to the rail.

Similar letters apply to similar parts throughout the several views. I

In the embodiment of the invention illus trated in the drawing, the rail is represented by A. The rail A is of the usual construction and has a head B and a base flange G and is supported upon a tie plate D, which in turn is supported upon the tie'E to which it is secured bythe spikes or screws F. The tie plate D1 maybe provided with a rib G arranged to engage one edge of the rail base C and has at the other side of therail base C an aperture H generally-similar to relates to devices known as the apertures "traversed by the spikes or screws F.

The shoe I is constructed to engage the upper surface and the edge of the rail base 0 at one side of the rail and this shoe I may be constructed with a portion K, which projects below the rail base C and engages the aperture H in the tie plate D. The shoe I: is formed with a groove L having ribs M at each side connected to stiffening ribs N and may be formed with a portion 0 which forms an aperture Q for a purpose to be later described. The groove L is preferably formed with a curved surface R for a portion. of the bottom of the groove, and the portionK of the shoe I has portions S projecting laterally. Another object is to provide a (lGVlCG.

The bar U has a portion V which extendsdownwardly below the edge and bottom of the rail base C and into the aperture H in the tie plate D, traversing this aperture and the aperture Q; in the shoe I. It has such form as to provide a curved surface W for engagement with the curved surface R at the bottom of the groove L of the shoe I and is arranged to be received in the groove L of theshoe I.

The device is applied to the rail, after the tie plate has been placed and secured in the customary manner, by placing the shoe in position on the rail with the portion K engaging. the aperture H in the tie plate D. In this position the portionsS of the por tion K of the shoe I will engage the two opposite sides of the apertureH in the tie plate D but the portion K of the shoe I will be free to slight lateral movements in the aperture H. The bar U is placed with the portion V traversing the aperture Q in the shoe I and its end entered in the aperture H of the tie plate D as illustrated in Fig. 4. When forced down until the head engaging portion Y of the bar U will just begin to engagethe under side ofthe head B of the rail A the curved surfacelVof the bar U will just begin to engage the curved surface R of the bottom of the groove L in the shoe I. The bar U may then be forced to the final operative position illustrated in Figs. 1, 2 and 3 by driving the upper portion of the bar U transverse to the rail until the head engaging portion Y of the bar U is in full engagement with the under surface of the rail head B. L In doing this the bar U is deformed, its shape beingchanged from that shown in Fig. 4' tothat shown in Fig. 1. The bar U during this process of forcing it into position will first fulcrum upon the curved surface R .of the bottom of the groove L in the shoe I and the portion V will engage the outer side of the aperture H in the tie plate D and exert transverse pressure upon the tie plate D pressing the rib G and the spikes or screws F againstthe opposite edge of the base C. As the bar U moves to position it is deformed and the surface engaging the surface R of the bottom of the groove L in the shoe is increased until in the final position of the parts the bar U engages the whole or nearly the whole of the bottom of the groove L in the shoe I. In this final operative position of the parts there is exerted by the bar U a pressure transverse to the rail pressing' the rib G and the spikes F against the edge of the rail base C, a pressure, transverse to the rail in the opposite direction, upon the shoe I pressing this shoe I upon the opposite edge of the rail base C, a downward pressure upon the shoe I which presses the shoe I downward upon the top surface of the rail base C, and a vertical pressure of the portion Y upon the under side of the .rail head B. The rail is in this way eflectu ally gripped by the device so as to hold it in position longitudinally upon the tie plate D and the tie E, but the rail is left free to the slight vertical movements of the rail in relation to the tie plate which wave motion of the rail may tend to produce. Moreover the bar U, in tending to resume its normal unstressed form is pressed up against the under side of the head B of the rail and this engagement of the portion Y of the bar U with the head B of the rail locks the parts in position, the bar U being held in position laterally by the engagement of the portion V With the tie plate D and the shoe I and being held in vertical position by the engagement of the portion Y which is pressed upwardly against the under side of the head B of the rail.

Should the rail tend to move in the direction of the arrow in Fig. 2 and the initial grip of the parts upon the railbe not sufficient to resist the stresses tending to produce this movement the rail will move slightly in the direction of the arrow. This movement will carry the upper portion Y of the bar U which is pressing up against the under side of the head B of the rail with the rail and the bar U will cant slightly and assume the position shown by the dotted lines in Fig. Qand will in this way increase the pressure of the bar U downward upon the shoe I and the shoe I downward upon the upper surface of the rail base 0 and in this way the grip of the device upon the rail will be automatically increased and the further movement of the rail in the direction ofthe arrow-prevented.

It will be understood that, should the tendency of the rail to creep be in a direction the reverse of that indicatedby the arrow, the action of the device will be the same but that the bar U will, if such creeping movement takes place, move slightly and cant in the direction opposite to that indicated by the arrows, in Fig. 2 and the movement of the rail will be self checked by the action of the device. The anchor, is thus effective in preventing creeping movement of the rail in either direction.

By suitablytt'orming the shoe I and the bar U they may be arranged to engage any spike aperture H in the tie plate D sothat they may be used with any tie plate already in use either by omitting one of the spikes orscrews For by drawing one which has been applied and substituting the shoe I and thebar U.

The bar U may be made in spring steel and, when made of this material and suitably tempered, the pressures exerted by the bar U upon the shoe I and the rail head B may be made as great as desired by suitably proportioning the bar. The bar" U need not necessarily be made of this material and the invention is not limited to the particular configuration illustrated, as it may be embodied in various other'forms.
